An implantable battery powered leadless pacemaker or biostimulator is provided that may include any of a number of features. One feature of the biostimulator is that it safely operates under a wide range of MRI conditions. One feature of the biostimulator is that it has a total volume small enough to avoid excessive image artifacts during a MRI procedure. Another feature of the biostimulator is that it has reduced path lengths between electrodes to minimize tissue heating at the site of the biostimulator. Yet another feature of the biostimulator is that a current loop area within the biostimulator is small enough to reduce an induced current and voltage in the biostimulator during MRI procedures. Methods associated with use of the biostimulator are also covered.
